DYNAMIC

    (Default) Enables dynamic mode. When dynamic mode is enabled,
    the debugger sets modules and images automatically during program
    execution so that you typically do not have to enter the SET
    MODULE or SET IMAGE command. Specifically, whenever the debugger
    interrupts execution (whenever the debugger prompt is displayed),
    the debugger automatically sets the module and image that contain
    the routine in which execution is currently suspended. If the
    module or image is already set, dynamic mode has no effect
    on that module or image. The debugger issues an informational
    message when its sets a module or image automatically.

 NODYNAMIC

    Disables dynamic mode. Because additional memory is allocated
    when a module or image is set, you might want to disable dynamic
    mode if performance becomes a problem (you can also free up
    memory by canceling modules and images with the CANCEL MODULE
    and CANCEL IMAGE commands). When dynamic mode is disabled, you
    must set modules and images explicitly with the SET MODULE and
    SET IMAGE commands.

 G_FLOAT

    Specifies that the debugger interpret double-precision floating-
    point constants entered in expressions as G_FLOAT (does not
    affect the interpretation of variables declared in your program).

 NOG_FLOAT

    (Default) Specifies that the debugger interpret double-precision
    floating-point constants entered in expressions as D_FLOAT (does
    not affect the interpretation of variables declared in your
    program).

 INTERRUPT

    Useful when debugging a multiprocess program. Specifies that,
    when program execution is suspended in any process, the debugger
    interrupts execution in all other processes that were executing
    images and prompts for input.

 NOINTERRUPT

    (Default) Useful when debugging a multiprocess program. Specifies
    that, when program execution is suspended in any process, the
    debugger take no action with regard to other process.

 KEYPAD

                                   NOTE

       This parameter is not available in the VSI DECwindows Motif
       for OpenVMS user interface to the debugger.

    (Default) Enables keypad mode. When keypad mode is enabled,
    you can use the keys on the numeric keypad to perform certain
    predefined functions. Several debugger commands, especially
    useful in screen mode, are bound to the keypad keys. (See the
    Keypad_Definitions_CI help topic; also, use the SHOW KEY command
    to determine the current key definitions.) You can also redefine
    the key functions with the DEFINE/KEY command.

 NOKEYPAD

                                   NOTE

       This parameter is not available in the VSI DECwindows Motif
       for OpenVMS user interface to the debugger.

    Disables keypad mode. When keypad mode is disabled, the keys on
    the numeric keypad do not have predefined functions, nor can you
    assign debugger functions to those keys with DEFINE/KEY commands.

 LINE

    (Default) Specifies that the debugger display program locations
    in terms of line numbers, if possible.

 NOLINE

    Specifies that the debugger display program locations as routine-
    name + byte-offset rather than in terms of line numbers.

 OPERANDS[=keyword]

    Specifies that the EXAMINE command, when used to examine
    an instruction, display the address and contents of the
    instruction's operands in addition to the instruction and
    its operands. The level of information displayed about any
    nonregister operands depends on whether you use the keyword BRIEF
    or FULL. The default is OPERANDS=BRIEF.

 NOOPERANDS

    (Default) Specifies that the EXAMINE command, when used to
    examine an instruction, display only the instruction and its
    operands.

 SCREEN

                                   NOTE

       This parameter is not available in the VSI DECwindows Motif
       for OpenVMS user interface to the debugger.

    Enables screen mode. When screen mode is enabled, you can divide
    the terminal screen into rectangular regions, so different data
    can be displayed in different regions. Screen mode enables you to
    view more information more conveniently than the default, line-
    oriented, noscreen mode. You can use the predefined displays, or
    you can define your own.

 NOSCREEN

                                   NOTE

       This parameter is not available in the VSI DECwindows Motif
       for OpenVMS user interface to the debugger.

    (Default) Disables screen mode.

 SCROLL

                                   NOTE

       This parameter is not available in the VSI DECwindows Motif
       for OpenVMS user interface to the debugger.

    Enables scroll mode. When scroll mode is enabled, a screen-mode
    output or DO display is updated by scrolling the output line by
    line, as it is generated. SET MODE SCROLL is the default.

 NOSCROLL

                                   NOTE

       This parameter is not available in the VSI DECwindows Motif
       for OpenVMS user interface to the debugger.

    Disables scroll mode. When scroll mode is disabled, a screen-mode
    output or DO display is updated only once per command, instead
    of line by line as it is generated. Disabling scroll mode reduces
    the amount of screen updating that takes place and can be useful
    with slow terminals.

 SEPARATE

    (Applies only to workstations running VWS.) Specifies that a
    separate window be created for debugger input and output. This
    feature is useful when debugging screen-oriented programs,
    because it moves all debugger displays out of the window that
    contains the program's input and output. The separate window is
    created with a height of 24 lines and a width of 80 columns wide,
    emulating a VT-series terminal screen.

 NOSEPARATE

    (Applies only to workstations running VWS. Default.) Specifies
    that no separate window be created for debugger input and output.

 SYMBOLIC

    (Default) Enables symbolic mode. When symbolic mode is
    enabled, the debugger displays the locations denoted by address
    expressions symbolically (if possible) and displays instruction
    operands symbolically (if possible). EXAMINE/NOSYMBOLIC can be
    used to override SET MODE SYMBOLIC for the duration of an EXAMINE
    command.

 NOSYMBOLIC

    Disables symbolic mode. When symbolic mode is disabled, the
    debugger does not attempt to symbolize numeric addresses (it
    does not cause the debugger to convert numbers to names). This is
    useful if you are interested in identifying numeric addresses
    rather than their symbolic names (if symbolic names exist
    for those addresses). When symbolic mode is disabled, command
    processing might speed up somewhat, because the debugger does not
    need to convert numbers to names. EXAMINE/SYMBOLIC can be used
    to override SET MODE NOSYMBOLIC for the duration of an EXAMINE
    command.

 WAIT

    (Default) Enables wait mode. In wait mode the debugger waits
    until all processes under its control have stopped before
    prompting for a new command.

 NOWAIT

    Disable wait mode. In nowait mode, the debugger immediately
    prompts for new commands even if some or all processes are still
    running.
